the same may be easily, quickly and accurately fed to its work and whichWlll operate on the work in an easy andpositive manner.

The foregoing objects, and others which will appear as the nature of theinvention 18 better understood, maybe accomplished by a construction,combination and operative arrangement of parts such as is illustrated bythe accompanying drawings, it being understood, however, that the natureof the device renders the same susceptible to changes in size,proportion and details of construction, all of such changes, however,falling within the scope of what is claimed.

In thedrawings:

Figure 1 is a side elevation of the improvement.

Fig. 2 is a front elevation thereof.

Fig. 3 is a sectional view approximately on the line 33 of Fig. 1.

Fig. 4 is a sectional view approximately on the line 4-4 of Fig. 2.

Fig. 5 is a detail view of the screw member carrying the beveled pinion.

Fig. 6 is a detail view of the sleeve or chuck. Fig. 7 is a detail viewof the bit or die.

Fig. 8 is a plan view of the head portion of the operating lever.

As disclosed by thedrawings I make use of a frame which is indicated bythe numeral 10. The frame is approximately centrally slotted from one ofthe ends thereof for the major portion of its length, thus providing ananvil arm 11 and an overlying arm 12 which is parallel but spaced fromthe anvil arm 11. The overlying arm has its outer end extended asuitable distance from the body of the frame proper, and this end isprovided with a round opening in which the bit or die 13 plays.

The bit or die 13 has its body portion round incross section and isprovided with an opening or bore 14 from its cutting edge 15, the saidbore terminating a suitable distance from the opposite end of the bit ordie, and the body of the die is provided with an opening 16 thatcommunicates with the bore 14. The body of the bit 13 has its endopposite its cutting end provided with an offset shoulder 1'7, thepurpose of which will presently be apparent.

On the upper and outer end of the frame 10 is secured a boxing 18 thathas a threaded opening 19 therethrough which alines with v the openingin the overlying arm 12 of the frame. The opening 19 in the boxing isthreaded, the said threads co-engaging with exterior threads 20 on acombined reciprocatory and rotary shaft 21. The lower end of the shaft21 is provided with a reduced threaded extension 22, and the threads ofthis extension are designed to be engaged by interior threads 23 on theupper end of a sleeve that provides a chuck member 24. The sleeve orchuck, inward of the threads 23 is formed with a longitudinally arrangedslot or notch 25 which is designed to recelve therein the shoulder 17 onthe bit 13.. The

bit 13 is first inserted through the chuck sleeve 24 from the threadedend thereof and when the shoulder 17 is received in the notch 25 aninterlocking engagement between the members 13 and 24 is obtained, Thechuck sleeve is then threaded on the extension 22 of the shaft 21.

On the end of the shaft 21, opposite that provided with the reducedthreaded extension 22 is keyed a beveled tooth wheel 26, and outward ofthe said toothed wheels the shaft 21 is provided with a reducedextension in the nature of a cross sectionally.

round spindle 27. This spindle 27 finds a bearing in a round opening 28arranged centrally of a bracket member29 that is secured to the frame10. The bracket is provided with extensions or arms on the oppositesides thereof which project upwith an opening arranged eccentric withrespect tothe toothed periphery of the said head and through thisopening the pin 31 passes. On the pin may be arranged sleeves to holdthe lever 33 against-lateral movement with respect to the device, andthe eccentric pivotal connection of the lever with the bracket perm-itsof the-teeth 35 at all times engaging with the teeth of the pinion 26.

The operation of the device will, it is thought, be perfectlyv apparentto those "skilled inthejart to which such inventions appertain. Thelever when swung in one direction will impart a combined rotary andlongitudinal movement to the bit in one direction of its work. Theaction of the bit on thework is by direct downward pressure and byrotary shearing orcutting'movement, so that holes may be made in beltseither of leather or fiber in an easy, quick and accurate manner. Thelever when swung in an opposite direction will raise the bit. It is, ofcourse, obvious that hits of various sizes may be employed, but in allinstances it is necessary to remove the chuck sleeve 24 from the shaft21 before thebit can be inserted in the said sleeve or removedtherefrom.

Having thus described the invention, what 1s clalmed as new, 1s:

1. In a belt punch, a frame includlng an anvil arm and an upper armoverlying the anv1l arm, a threaded boxing carried by the upper arm, athreaded shaft engaging said boxing, a bit guided through an opening in"said arm, a chucksleeve having'a locking engagement with the bit andremovably con nected to the lower end of'the shaft, and means forimparting motion to the shaft whereby a simu-ltaneousrotary and longitudinal movement is imparted to the bit.

' 2. In a belt punch, a frame including an arm and disposed parallelthereto, a boxing having interior threads on the upper arm, {a threadedshaft engaging the threads in the boxing, a bit guided-through anopening in' the said arm, a chuck sleeve having a looking engagementwith the bit removably secured to the lower end of the shaft, guidemeans for theupper end of the shaft, a pinion secured to thefup-per'endof the shaft, an operating lever pivotally connected to the frame havinga segmental headed portion which is provided with teeth arrangedeccentrically with respect tothe pivot which teeth engage-withthe pinionand by virtue of the arrangement thereon with: respect to the plvotcontlnue 1nmeshing engagement with the pinion when the shaft israised'or lowered withthe pinionand a combined reciprocatory and rotarymovement iniparted'to the bit V In testimony whereof'I affix mysignature.
